A cool feature to add with the keybinding would be controller support to the engine. Or at least be able to customize it, certain games can't really function with a controller cause of the scripts and stuff. I feel like it would go well within the "Layout" tab within the keybinds in the options
Another good suggestion would be to make the in-engine settings be able to change with scripts.
Also, make it so that we can change the Icons for our projects, or make it more customizable for people. (callme-jk inspired this part)
That's all for now
